Speed

  • 2 third-party services on the page

    2 third-party services load with your homepage (Google Tag Manager and Google Analytics), adding 289 KiB and 142 ms of main-thread time.

  • Font display

    50 ms

    Web fonts hide text while they load. Setting font-display: swap shows text immediately (about 50 ms).

2 checks passed

  • Main-thread work: 0.8 s

    A phone's processor spends 0.8 s on main-thread work while loading, 429 ms of it running JavaScript. That is comfortably low.

  • Server response: 21 ms

    21 ms

    Your server sent the HTML in 21 ms, well inside Google's 600 ms guideline.

Core Web Vitals

1 to fix100

  • First Contentful Paint: 1.8 s

    1.8 s

    The first text or image appears after 1.8 s on a phone. Good is under 1.8 s.

  • Not enough real-visitor data yet

    Chrome's UX Report (opens in a new tab) has too little real-visitor traffic for this site, so the figures here are lab measurements from Google's test phone on a throttled 4G connection.

2 checks passed

  • Cumulative Layout Shift: 0

    0

    The layout barely moves while loading (CLS 0, good is under 0.1).

  • Speed Index: 1.8 s

    1.8 s

    Visually, the page fills in at 1.8 s (Speed Index), inside the 3.4 s “good” threshold.

Images and page weight

100

  • About 0.2 g of CO₂ per visit

    0.19 g

    By the Sustainable Web Design model, a visit to your homepage emits about 0.19 g of CO₂e: 22.4 kg a year at 10,000 visits a month. It scales with page weight, so every byte cut lowers it.

1 checks passed

  • Page weight: 676 KiB in 20 requests

    676 KiB

    Your homepage downloads 676 KiB in 20 requests on a phone: other files 323 KiB (10), scripts 308 KiB (6) and HTML 25 KiB (1). That is a lean page.

Accessibility

2 to fixGoogle 9795

  • All page content should be contained by landmarks (1 element)

    All page content should be contained by landmarks: 1 element on the page fails this check, rated moderate by axe-core.

  • The skip-link target should exist and be focusable (1 element)

    The skip-link target should exist and be focusable: 1 element on the page fails this check, rated moderate by axe-core.

1 checks passed

  • 18 automated accessibility rules passed

    axe-core 4.13.0, the open-source engine behind most accessibility testing tools, ran 20 WCAG 2.2 A/AA and best-practice rules on the phone render: 18 passed and 2 failed. Automated rules catch about a third of accessibility problems; the rest need manual testing.

SEO

4 to fixGoogle 10080

  • No H1 headline

    There is no <h1>, so neither visitors nor Google get a clear main headline.

  • No structured data

    No structured data (JSON-LD), so Google can't show rich results such as your logo, ratings or FAQs.

  • No XML sitemap

    No XML sitemap at https://hellokarthic.com/sitemap.xml, so Google discovers your pages only by following links.

  • Only 0 internal links

    The homepage links to only 0 pages on your own site, so visitors and crawlers find few routes into the rest of it.

5 checks passed

  • Meta description: 148 characters

    Your meta description is 148 characters: “Karthickeyan Narasimhan is a software engineer based in Chennai, India who specializes in buildingscalable, efficient, …”.

  • Title: 50 characters

    Your title is a healthy 50 characters: “Karthickeyan Narasimhan | Senior Software Engineer”.

  • Canonical URL set

    The canonical URL is https://hellokarthic.com/.

  • Open Graph tags complete

    Open Graph tags are complete, so shared links show a title, description and image.

  • robots.txt in place

    robots.txt is in place and points crawlers to your sitemap.

AI search readiness

1 to fix83

  • No Organization structured data

    There is no Organization (or LocalBusiness) JSON-LD, so search engines and AI assistants have no machine-readable facts about who runs the site: its name, logo, profiles and contact details.

  • No llms.txt

    There is no /llms.txt, a short Markdown guide to your key pages for AI tools (llmstxt.org). It is optional and few AI tools read it yet, so treat it as a cheap extra.

1 checks passed

  • AI answer engines may read the site

    Your robots.txt lets the crawlers behind ChatGPT search, Claude and Perplexity read the site and cite it in answers.

Best practices

1 to fixGoogle 10092

  • 1 JavaScript error while loading

    1 error was logged to the browser console while the page loaded, for example “Cannot read properties of undefined (reading 'register')”.

1 checks passed

  • Mobile viewport set

    The page declares a mobile viewport.

Security and trust

1 to fix92

  • No Content-Security-Policy

    No Content-Security-Policy header, the main browser-side defence against injected scripts.

  • No clickjacking protection

    Neither X-Frame-Options nor a CSP frame-ancestors policy is set, so any site can embed yours in a frame.

  • No X-Content-Type-Options

    X-Content-Type-Options: nosniff is missing, so browsers may guess file types.

  • No Referrer-Policy

    No Referrer-Policy header, so full URLs can leak to the sites you link to.

  • No Permissions-Policy

    No Permissions-Policy header to switch off camera, microphone and location for embedded content.

  • No security.txt

    There is no /.well-known/security.txt telling researchers how to report a security problem to you.

5 checks passed

  • Served over HTTPS

    The homepage is served over HTTPS (hellokarthic.com).

  • Valid certificate (46 days left)

    The certificate from Let's Encrypt · YE2 verifies for hellokarthic.com and is valid for another 46 days.

  • HSTS enabled

    Strict-Transport-Security is set, so browsers always use https.

  • http:// redirects to https

    http://hellokarthic.com redirects to the secure version.

  • HTTP/2

    The server speaks HTTP/2, so browsers load many files over one connection.

Domain and trust

  • No CAA record

    hellokarthic.com has no CAA record, so any certificate authority may issue a certificate for it. A CAA record naming your provider (for example letsencrypt.org) closes that door.

Content and conversion

5 to fix33

  • No call to action on the first screen

    On a phone, there is no call to action on the first screen: visitors have to scroll to find out what to do next.

  • No calls to action

    We found no call-to-action buttons or links (such as “Book a demo” or “Get a quote”) anywhere on the homepage.

  • No social proof

    No testimonials, customer logos, ratings or customer counts on the homepage: nothing tells a new visitor that others already trust you.

  • No direct contact details

    No phone number or email link on the homepage, so ready-to-buy visitors have one fewer way to reach you.

  • Only about 3 words

    The homepage has only about 3 words of visible text; thin pages give Google and first-time buyers little to go on.

  • No form on the homepage

    There is no form on the homepage, so every lead has to click through to another page first.

  • No risk reducer

    No guarantee or risk reducer (money-back, free trial, no credit card) is mentioned, which is often what tips a hesitant visitor.

1 checks passed

  • Analytics in place

    Analytics detected: Google Analytics.

Email authentication

2 to fix0

  • No DMARC policy

    hellokarthic.com has no DMARC record, so nothing tells receivers what to do with mail that fails SPF or DKIM. Gmail and Yahoo require DMARC from bulk senders.

  • No SPF record

    hellokarthic.com has no SPF record, so mail servers can't tell which servers may send email as you. Your mail lands in spam more often, and anyone can send mail pretending to be you.

  • No DKIM key on the usual selectors

    We found no DKIM key on the selectors the big email providers use. If you send through one of them, turning on DKIM signing improves delivery.

  • Domain receives no email

    hellokarthic.com has no MX record, so it receives no email. SPF -all and DMARC reject still matter: they stop others sending mail as you.

  • Email authentication score: 0/100

    Email authentication: SPF record 25 points, plus 15 when it ends in -all (10 for ~all); DMARC record 25, plus 25 for a reject policy (15 for quarantine); a DKIM key on a common selector 10.

Privacy and tracking

1 to fix

  • 2 trackers load before any consent

    2

    Before a visitor clicks anything, the page loads Google Analytics and Google Tag Manager (measured from a US location before any click). No consent tool was detected. Visitors from the EU, UK and several US states must be asked first.

  • 3 cookies set on arrival

    3

    Opening the homepage sets 3 cookies (measured from a US location before any click).

  • No consent tool detected

    No known cookie consent tool loads with the page. Some sites build their own banner, and some only show one to visitors from the EU.

  • 2 other companies contacted

    Loading the homepage contacts 2 hosts run by other companies (fonts, scripts, analytics, ads), each of which sees the visitor's IP address.
